  • Patent number: 9181816
    Abstract: A seal assembly between a disc cavity and a hot gas path in a gas turbine engine includes a stationary vane assembly and a rotating blade assembly axially upstream from the vane assembly. A platform of the blade assembly has a radially outwardly facing first surface, an axially downstream facing second surface defining an aft plane, and a plurality of grooves extending into the second surface such that the grooves are recessed from the aft plane The grooves are arranged such that a circumferential space is defined between adjacent grooves During operation of the engine, the grooves impart a circumferential velocity component to purge air flowing out of a disc cavity through the grooves to guide the purge air toward a hot gas path such that the purge air flows in a desired direction with reference to a direction of hot gas flow through the hot gas path.

  • Patent number: 8968838
    Abstract: A method is provided for exciting at least one electrode of a capacitively coupled reactive plasma reactor containing a substrate. The electrode is excited by applying a RF voltage with a trapezoidal waveform comprising a ramp-up, a high plateau, a ramp-down and a low plateau. The plasma density can be controlled by adjusting the duration of the ramp-up, the duration of the ramp-down, the amplitude and the repetition rate of the trapezoidal waveform. The ion energy distribution function at the substrate can be controlled by adjusting the amplitude and the relative duration between the high plateau and the low plateau of the trapezoidal waveform.

  • Patent number: 8922362
    Abstract: A plurality of hazard alarm devices are in spatially diverse locations and coupled together with an input-output bus. An interconnect protocol enables non-originating alarm devices to synchronize their audible alert tone pulses with audible alert tone pulses from an originating alarm device in a local hazard alarm condition. Hence, all audible alert tone pulses start sounding substantially together with allowances for signal contention and arbitration between the spatially diverse alarm devices.

  • Patent number: 8723672
    Abstract: A plurality of hazard alarm devices are in spatially diverse locations and coupled together with an input-output bus. An interconnect protocol enables non-originating alarm devices to synchronize their audible alert tone pulses with audible alert tone pulses from an originating alarm device in a local hazard alarm condition. Hence, all audible alert tone pulses start sounding substantially together with allowances for signal contention and arbitration between the spatially diverse alarm devices. The originating alarm device continuously sounds its pattern of audible alert tone pulse groups without interruption, while the non-originating alarm devices periodically pause sounding a group of their audible alert tone pulses. The originating alarm device may be found by listening for the alarm device that is continuously sounding audible alert tone pulse groups without pause.

  • Patent number: 8448204
    Abstract: Systems and methods for aggregating user data and targeting content to users are described. User data is collected through quizzes and users are associated with a particular fictional or nonfictional character profile based on the user-submitted information. The user data associated with each character profile is aggregated to identify and recommend content for the user, such as television shows, news feed, web pages, promotions, advertisements, and the like. The invention can be used in connection with fan sites or other topic-specific sites that are associated with the character of the character profile.

  • Publication number: 20120078665
    Abstract: When presenting information to a user via a display, an animated timeline (18) is provided on which a user selects a tick mark (74, 92) representing a time on the timeline (18), to view data collected at that time. A time window (72) of a predetermined width (e.g., an hour) is centered on the selected tick mark (74, 92), and the timeline (18) is then animated as it shifts the selected tick mark (74, 92) to the center of the timeline (18). Data (e.g., images, measured parameters, etc.) corresponding to the time window is identified (e.g., via timestamp information) and presented to the user on a display along with the timeline (18).

  • Patent number: 7976932
    Abstract: A ballistic resistant panel including a strike face portion and a backing portion. The strike face portion includes a plurality of interleaved layers of non-fibrous ultra high molecular weight polyethylene tape. The backing portion includes a plurality of interleaved layers of cross-plied fibers of ultra high molecular weight polyethylene. The entire stack of interleaved layers is compressed at high temperature and pressure to form a ballistic resistant panel having a strike face on one side. It has been found that ballistic resistance increases as the weight ratio of the strike face portion with respect to the backing portion decreases. A composite panel having a strike face Tensylon tape with at most 40% of the total weight of the panel exhibits improved ballistic resistance properties as compared to a monolithic structure of strictly interleaved layers of cross-plied high modulus fibers.

  • Patent number: 7972679
    Abstract: A ballistic-resistant molded article having a sandwich-type structure including two outer portions of a first high modulus material surrounding an inner portion of a second high modulus material. The outer portions are comprised of a plurality of interleaved layers of adhesive coated cross-plied non-fibrous ultra high molecular weight polyethylene tape. The inner portion is comprised of a plurality of interleaved layers of high modulus cross-plied fibers embedded in resin. The stack of interleaved layers is compressed at high temperature and pressure to form a hybrid sandwich ballistic-resistant molded article that includes a mix of high modulus materials. It has been found that ballistic resistance is higher for the hybrid structure than for a monolithic structure of comparable areal density.
